        ContraVir to Expand Hepatitis B Portfolio through Strategic Merger Agreement with Ciclofilin Pharmaceuticals               

                        Conference Call to be Held Today at 8:30 a.m. ET               

                                                                                                                        

06:00 ET    from ContraVir Pharmaceuticals, Inc.                                

                                    
  
                                                                                                                                                                                                                           

EDISON, N.J., May 31, 2016 /PRNewswire/ -- ContraVir Pharmaceuticals, Inc. (NASDAQ:   [url=]CTRV[/url]), a biopharmaceutical company focused on the development and commercialization of targeted antiviral therapies, announced today that it has entered into a definitive merger agreement with privately-held Ciclofilin Pharmaceuticals, Inc. pursuant to which ContraVir will acquire all of the outstanding equity interests in Ciclofilin for the right to receive future milestone payments which will be allocated among the holders of Ciclofilin common stock.  The milestone payments will consist of up to an aggregate $17 million cash and up to 10% of ContraVir's issued and outstanding common stock as of the closing date of the merger, and will be paid upon the achievement of certain developmental and/or regulatory milestones related to CPI-431-32, Ciclofilin's lead development candidate.  

                                                                                 

CPI-431-32 is a next-generation non-immunosuppressive cyclophilin inhibitor shown to have best-in-class potency against hepatitis B virus (HBV) and a significantly larger selective index compared to previously known cyclophilin inhibitors. It is anticipated that this large selective index will provide a meaningful degree of clinical utility in the treatment of chronic HBV infection.  Upon completion of the merger, Ciclofilin's Founder and CEO Robert Foster, Pharm.D., Ph.D., will join ContraVir in the role of Chief Scientific Officer, and will continue leading the development of CPI-431-32 into IND-enabling studies.  

                                                                                                                                 

The merger will expand and strengthen ContraVir's portfolio of complementary antiviral candidates targeting HBV, which includes CMX157, a highly potent lipid conjugate of tenofovir, currently undergoing Phase 1b/2 clinical trials.  ContraVir will remain headquartered in Edison, NJ, and will acquire Ciclofilin's R&D facilities in Edmonton, Canada.

                                                                                 

James Sapirstein, CEO of ContraVir, stated, "Completing this strategic transaction will firmly position ContraVir as an important player in the hepatitis B space.  Similar to our clinical stage candidate CMX157, we will add to our portfolio what we believe is a superior molecule that improves significantly upon the established efficacy and safety of the class of compounds from which it is derived, thereby enhancing its clinical utility as an antiviral.  Furthermore, the mechanism of action of CPI-431-32 is complementary to CMX157, each inhibiting distinct critical steps in the viral life cycle, adding robustness to our HBV portfolio.  We look forward to completing the merger and to continuing the pre-clinical development of CPI-431-32 in preparation for potentially entering the clinic in 2017."

                                                                                 

CPI-431-32 is a highly potent derivative of cyclosporine, yet is engineered to be non-immunosuppressive.  It selectively targets and inhibits host cellular enzymes known as cyclophilins (CyP), which are commonly recruited by HBV and other viruses as part of their normal life cycle.  CPI-431-32 blocks HBV's ability to "hijack" CyP, and has also been shown to inhibit entry of HBV into liver cells as well as reduce or eliminate production and secretion of key hepatitis B antigens (HBsAg and HBeAg).  In vivo studies also demonstrated CPI-431-32's ability to reduce liver HBV DNA without significant toxicity.  It is this optimized selective index that distinguishes CPI-431-32 and improves upon previous cyclosporine derivatives.  Cyclosporines have been used clinically for more than 30 years in the field of organ transplant and more recently have been dosed in more than 2,000 patients as a treatment for chronic hepatitis C infection.  Finally, CPI-431-32 is expected to be effective against all HBV genotypes due to the fact that it inhibits host enzymes that are common to the life cycle of all HBV sub-types.

                                                                                 

Robert Foster, Pharm.D., Ph.D., Founder and CEO of Ciclofilin, commented, "CPI-431-32 is positioned to be the leading non-immunosuppressive cyclophilin inhibitor antiviral for the treatment of hepatitis B.  My team and I are excited to join ContraVir to accelerate development of this asset, based on ContraVir's deep understanding of HBV and clear dedication to providing needed therapies for this complex, chronic infection.  Both CPI-431-32 and CMX157 have demonstrated best-in-class potential and have the benefit of positive clinical experience using related compounds, creating a very strong hepatitis B pipeline."

                                                                                 

The merger, which has been approved by the Board of Directors of both companies, is subject to customary closing conditions.  Following the completion of the transaction, Ciclofilin will become a wholly owned subsidiary of ContraVir.

ContraVir通过与Ciclofilin制药战略合并协议展开乙肝投资组合

电话会议今天在上午8:30 ET举行

从ContraVir制药公司ET 06:00

EDISON,NJ,2016年5月31日/新华美通/ - ContraVir制药公司(纳斯达克股票代码:CTRV),一家生物制药公司的发展重点和有针对性的抗病毒疗法的商业化,今天宣布,它已进入了最终合并协议私人持有Ciclofilin制药公司,据此,ContraVir将收购全部Ciclofilin优秀的股权合适的接收将的Ciclofilin普通股持有人之间进行分配未来的里程碑付款。具有里程碑意义的款项将包括ContraVir的发行在外的普通股作为合并完成日的最高合计$ 17百万现金和高达10%,并在相关的某些发展和/或监管里程碑的实现将支付以CPI-431-32,Ciclofilin的超前发展的候选人。

CPI-431-32是显示具有最佳的类抗乙型肝炎病毒(HBV)和比较先前已知的亲环蛋白抑制剂一个显著更大选择性指数效力下一代非免疫抑制性亲环抑制剂。据预计,这个大选择指数将提供临床应用的慢性HBV感染的治疗一个有意义的程度。一旦合并完成后,Ciclofilin的创始人兼首席执行官罗伯特·福斯特,药学博士,博士,将加入ContraVir的首席科学官的角色,并将继续引领CPI-431-32的发展注入IND启用研究。

该合并将扩大和加强互补抗病毒药考生瞄准HBV,其中包括CMX157,替诺福韦的一个高度有效的脂质缀合物,目前正在1b期/ 2的临床试验ContraVir的投资组合。 ContraVir总部仍将留在新泽西州Edison,并且将收购加拿大埃德蒙顿Ciclofilin的研发设施。

詹姆斯Sapirstein,ContraVir的CEO表示:“完成这一战略性交易将牢牢定位ContraVir作为乙肝领域的一种重要的球员。我们的临床阶段的候选CMX157类似,我们将增加我们的投资组合我们认为是一种高级的分子于类化合物从其所衍生的,从而提高其临床效用作为抗病毒药的既定疗效和安全性显著提高。此外,CPI-431-32的作用机制是对CMX157,每个抑制不同的关键步骤互补在病毒的生命周期,增加的鲁棒性,我们的投资组合HBV。我们期待着在完成合并,并继续CPI-431-32的制剂临床前开发在2017年有可能进入诊所“

CPI-431-32是环孢素的高度有效的衍生物,但被改造为非免疫抑制。它选择性靶向并抑制被称为亲环(CYP),其通常由乙肝病毒和其他病毒招募作为其正常生命周期的一部分宿主细胞酶。 CPI-431-32块的HBV的“劫持”的CyP的能力,并且也已显示出抑制乙肝病毒的进入肝细胞,以及减少或消除键乙型肝炎抗原(HBsAg和HBeAg)的产生和分泌。在体内研究还证实CPI-431-32的减少肝脏HBV DNA没有显著的毒性的能力。它是区分CPI-431-32和改进了以前的环孢菌素衍生物此优化选择指数。环孢菌​​素已经在临床上使用了超过30年的器官移植领域,最近在2000多名患者已经剂量为慢性丙型肝炎感染治疗。最后,CPI-431-32预计是针对由于它抑制宿主的酶,它们共同所有的HBV亚型的生命周期的事实所有HBV基因型有效。

罗伯特·福斯特,药学博士。Ciclofilin的博士,创始人兼首席执行官,评论说:“CPI-431-32被定位为用于治疗乙型肝炎的我和我的团队的主要非免疫抑制亲环素抑制剂抗病毒很高兴加入ContraVir加速该资产的基础上,ContraVir的HBV和清晰的奉献精神的深刻理解发展提供所需的疗法这种复杂的,慢性感染。这两种CPI-431-32和CMX157已经证明最好的一流的潜力和有使用相关化合物,营造出非常强的乙肝管道积极的临床经验中获益。“

合并后,已批准两家公司的董事会,还取决于惯例成交条件。在交易完成后,Ciclofilin将成为ContraVir的全资子公司。
